This article explains a 3 way switch wiring diagram and step How to wire three way light switch electrical circuit We have to discuss about what are the three ways for wiring diagram as discussed below and how to connect all the lights and what are the different techniques to join such switches to getour own desired outputs as mentioned below. We will also develop kind of topics as multiple switching and single switching connections for connecting light switches as three way switching and wirings.

To give you an understanding how to connect this complicated switch as by three ways called three way light switches. Also showing by the help of pictures to clarify the correct connection of the switch that helps to light up huge halls or long streets at only one touch as one or two switches connected to each other controlling the whole scenario.

Important Cautionary Note!You want to make sure that you are being safe and that means that you need to turn off the power to the circuit that you are working on. You want to make sure that you are working with a tester and that you also check this as well on your own.

3 Way Switch Wiring Diagram with Power
Feed Via Switch :

You will see what you need to do when the power is coming to the light switch. The power source also connects the terminal main three-way switch and means that you need to have it spliced with a 3 way switch with the wire cable and that you will see the way that there is a neutral terminal with the light. When the hot is connected from the terminal to the hot of the light you will have completed this correctly.

3 Way Switch Wiring Diagram with Power Feed Via Light :

Now discussing 3-way light switch wiring diagram as also discussed above the color codes of the
wires as having three insulated conductors as black as hot, red as switch wire or called traveler
and white as common wire as also shown when light is connected to both black and white
wires.
The main difference between the ‘figure A’ and ‘Figure B’ are that ‘Figure A’ didn’t involve
power source to the light while Figure B involve power source. Using wire nuts to attach green
wires together that it’s important for connecting 3-way switch for lightening a bulb or light as
also shown in diagram above.
As you observe we have four type of wires here having yellow cap with green wires to cover the
short circuiting if any fault occurs. The most common way to wire a 3-way switch while want to
light-up of your staircase or hallway. Light switch at one end, lights in the middle, light switch at
the other end and its simple. Trace the wires carefully in the diagram so you can connect them
to the proper locations. Also choose (12-3) 3-wire Romex with ground for short-circuit safety
from 3-way switch that we have to cover all aspects for our own safety.

3 way light switch wiring diagram poower source feed via light :

First you have to turn off the correct electrical panel circuit by adding this electrical box for the three-way switch in that place or called basement. You have also to make space for the three way switch because of many wires then single switch. While also showing above in the circuit having three insulated conductors as black as hot, red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires. Having length of 14-3 type NM cable (or 12-3, if you’re connecting to 12-gauge wire) between the two boxes as shown in the figure above named as 3 wire ROMEX with ground*(12-3). Connecting these wires to the new three-way switches with ground as shown above. Be sure to wrap black or yellow as shown above an electrical tape around the ends of all white wires that are used as travelers between the three-way switches. If you have the setup shown in Fig. A, also wrap black tape around the white wire from the switch to the light. This way, both you and others will know these wires are “hot” and not neutral like most white wires.

There the scenario is changed we have to connect two lights using two 3-Way switch mechanisms we have to just add one more light in between the first light and one of the 3-way switch. Follow the wire colors to connect them easily or electrician will be better for making the circuit more easily.

Actually the diagram explains everything clearly while controlling by two 3-way switches with a two wire
cable power supply as shown. Remember only two wire cable with ground is necessary for the boxes at
the lights we see there. Traveller wires (red in color) connect the three-way switches without going in
deep to the system or circuit given.

If, you are fed up of electrical faults occurring repeatedly, then you must not ignore such situations, because it might be sign of a risky wiring. Why not try to visit our homepage and contact us online? We will help providing long lasting remedy to all electrical errors.

I was about to buy a new home, so I called up electrical specialist who inspected the home for electrical faults with utmost care, because it is the most essential point to be considered before finalizing the deal.
